Abstract

一种人体感应自动工作的LED球泡灯，应用人体感应传感器为驱动载体，通过有关电路使LED球泡灯，在有人走进灯泡附近时自动亮；而在人走开后灯自动关灯。起到既省电能，又使LED球泡灯的使用寿命增强的功能。

Description

一种人体感应自动工作的LED球泡灯
技术领域
本发明涉及一种人体感应自动工作的LED球泡灯。
背景技术
在一些住宅楼的楼梯口安装的灯，晚上无人走动时，灯具炽亮的工作显然是个电能上的浪费，又是使灯具减少使用寿命；在家庭的卫生间用的灯具晚上只要有人进卫生间灯光就亮，显然是很方便。
发明内容
本发明一种人体感应自动工作的LED球泡灯，公开一种以人体感应为传感器，通过放大电路作用驱动LED球泡灯亮，然后当人走开后，LED球泡灯又自动关灯，起到即省电又使LED球泡灯长久耐用的功能。
一种人体感应自动工作的LED球泡灯，其电路组成由整流电路、晶闸管开关电路、稳压电路、人体感应电路、功率开关电路和LED灯电路组成。
附图说明
图1是一种人体感应自动工作的LED球泡灯的电路原理图。
具体实施方式
如图1所示，D1、D2、D3、D4组成单相桥式整流电路，把交流220V变成脉动的直流电。R1、R2、R3、C1、C2、D5组成晶闸管开关电路，R3是可调电阻，当R3往左移动时，晶闸管D5的导电开度大，输出的电流大；当R3往右边移动时，晶闸管D5的导电开度小，输出的电流小。通过调节R3的阻值，即可满足所需的LED灯的电流值。
如图1所示，D6是双端稳压电路，选用稳压值为12V的稳压管，它把脉动的直流电变成文定的直流电供给LED灯的工作电源。
如图1所示，IC1时人体感应传感器电路，1脚接负电源；3脚接正电源；2脚为输出端。当无人在传感器的有效工作范围走动时，IC1的输出脚2无信号输出，三极管T截止，此时IC2的5脚电为为低电平，IC2不导通；当有人在传感器的有效工作范围走动时，IC1的2脚输出高电平信号，驱动三极管T由截止变为导通，此时，IC2的5脚电为为高电平，使1脚的电压输出到2、3脚，LED灯亮。
如图1所示，IC2时功率开关电路，型号为TWH8778，其5脚是使能端，当5脚的电压低于1.6V时，IC2截止；当5脚的电压高于1.6V以上时，IC2导通。
如图1所时，V是压敏电阻，在电路中起瞬间管电压保护；C3是滤波电容器，在电路中起到延时IC2导通时间的作用。
